Abstract

Se proporciona un catalizador y un método para reducir selectivamente los óxidos de nitrógeno ("NOx") con amoniaco. El catalizador incluye un primer componente que comprende una zeolita o una mezcla de zeolitas, un segundo componente que comprende al menos un miembro seleccionado del grupo que consiste de cerio, hierro, cobre, galio, manganeso, cromo, cobalto, molibdeno, estaño, renio, tantalio, osmio, bario, boro, calcio, estroncio, potasio, vanadio, níquel, tungsteno, un actínido, mezclas de actínidos, un lantánido, mezclas de lantánidos, y mezclas de los mismos, opcionalmente un material de almacenamiento de oxígeno y opcionalmente un óxido inorgánico. El catalizador reduce selectivamente los óxidos de nitrógeno a nitrógeno con amoniaco a altas temperaturas. El catalizador tiene una alta estabilidad hidrotérmica. El catalizador tiene alta actividad para la conversión de bajos niveles de óxidos de nitrógeno en corrientes de gases de escape.
